Britney Slags Off Paris' Mutt

Britney and muttThere's not much love lost between Britney Spears and Paris Hilton.

And now the popstar has pushed it to the limit by starting up a catfight by slagging off Paris' dog.

Both stars are fans of the chihuahua mutt - and are rarely seen without a tiny pooch sticking out of their handbag.

But Britney has dared to offend Paris' pup, Tinkerbell, in the same breath as bigging up her own little pets, Bit Bit, Lacy Loo and Lucky.

"My dogs are stylin' and profilin," the Toxic singer wrote on her website.

"Von Dutch just sent them the coolest little clothes. My dogs are so much cuter than Tinkerbell," she said.

"A lot of people admire Tinkerbell's look," she said. "So I included a glamorous pet collar."

The two blonde celebs are not the only stars who've jumped on the weeny dog bandwagon, with Geri Halliwell and Jessica Simpson also fond of socialising with their dogs in tow.
